DESY Phone Book

A query is executed case insensitive. It is possible to use wildcards * and ? in place of multiple and single characters.

A query is done by string matching independent of the order of strings within each field. But using the exact query option, order and string structure become
important. Note, searching with the exact option in the name field includes to take into account the general order of firstname lastname, which is different to
the result page.

There are restrictions in the usage of query strings to avoid misusage. Filled out fields must at least consist of two alphanumeric character. The query string
within the name field must consist of at least a alphanumeric string of three characters.
